Car Key Programming

A lot of vehicles, particularly high-end ones, require that only the dealer be allowed to make new keys.
The method to do this yourself is different from manufacturer to manufacturer. It typically involves inserting the spare key that works into the ignition and manipulating it (in accordance with the directions in the owner's manual) until your car is in programming mode. You'll need to be quick to complete the procedure, since it only lasts a few seconds before your car leaves the mode.

The instructions in the owner's manual must be specific to the type of key and model you're trying to program, as certain models have additional security features that need to be activated (for instance the passcode required to access certain programming modes).
Certain models also require a code that you can only get through a dealer for a cost. This code guards against "skimming" which occurs when thieves attempt to read the information on your key through the OBD2 ports to steal the vehicle.
It's a great method to save money, but if the key isn't set up correctly, it won't be able to unlock or start your car. A reputable auto repair shop like J.C.
